Application filed December 27,1904. Renewed May 18, 1906. Serial No. 317,420.

To all whom it may concern.-

Be it known that I, JAMES H. MITCHELL, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Pa er Boxes, of which the following is a true an exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relatesto the construction of paper boxes provided with an interior lining such, for instance, as are desirable for use in packing biscuitmy object being to provide a box of this character of novel construction which will be sufficiently moisture proof without requiring an outer cover of paper and which will also be of such character and construction that the labels and decorations usually applied to such packages can be printed directly on the box itself.

The nature of my improvements will be best understood as described in connection with the drawings, in which they are illustrated, andin which- Figure 1 illustrates the method of forming the inner box or lining of the package. Fig. 2 is a plan view of a blank which I prefer to use for the outer casing or box proper. Fig. 3 illustrates in connection with the description the various steps of folding the blank over and around the inner lining of the box. Figs. 4 and 5 show the steps of closing the box; and Fig. 6 is an exaggeratedsectional view through the end of the box as on line 6 6 of Fig. 5, showing the mode in which the cementing material holds the flaps of the outer box together and to the end wall of the inner box or lining.

Referring first to Fig. 1, A indicates a sheet of paper of suitable character for a boxlining, and C the former over which the paper can be folded to the requisite form. As shown, the paper, placed on the former, as shown in Fig. 1, is first folded,down on the lines A A and then the ends folded down and creased on the lines A This also results in or is immediatel followed by the a formation of the diagonal olds AA, and the inner-box lining is then completed to the form it occu ies before the closure of the ackage by olding in the end flaps on the ines'A A &c.

My preferred form of blank for the outer casing, as shown in .Fig. 2, has, extending out from the ends of the section B, which forms the bottom of the box,.the end flaps B B,

which are perforated, preferably by slotted peforrations arranged in diagonal lines, as indicated at B The portionspf the blank which form the front and back walls of the box and which are marked B and B are also provided with end fla s, of which the ones which are to be inner aps B B, for instance, are formed with perforations, as in dicated at B, while the end flaps B B, Which are the outer flaps of the box, are formed without perforations, as shown. By preference I form my blank also with the laterally-extending flaps B B extending from the sides of the flaps B and also, by preference, I provide the front wallB with a narrow terminal flap B and the rear wall B with a broad cover-fl p, (indicated at B In assembling the box the blank B is placed on the former, as indicated in Fig. 3, and the inner end flaps B B turned down u on the ends of the lining-box, as shown. T e-front and back walls of the blank are then bent down over the former, as shown, and, preferably at this time, cementing materialis applied to the perforated flaps B B. The cementing material which I prefer to employ is sealing-wax of proper consistency. T e perforated flaps B B are then turned in on the -flaps B and the outer end fla s B B are then folded in a ainstthe ends 0 the box and pregsure ap lie which will cause the cementmg materia applied to the flaps B to force its way through and between the perforated flaps and through the inner perforated flap into contact with the inner lining and beneath the folds A of thislining, the disposition of the cementing material being indicated in the distorted view, Fig. 6, where the distributed cement is shown at E. The lined box is then removed from the former C, and after it has been filled with biscuit or other material the top flaps are folded down, as shown in Figs. 4 and 5, and sealed or secured in place. By preference the top flaps B B are folded m, as shown in Fig. 4, pressing the upstanding end walls of the inner lining down upon the contents ofthe box and causing the formation of the angular front and rear flaps A A. The narrow top fla B is then folded down,

ressingthe front aps A with in and-then y reference lines or dots of cementing material? as indicated at F, Fig. 5, are applied to the end flap B and the outer ed e' of the flaps B, B The package is fina y closed, preferably by first folding down the flap A,

the end" of which may be tucked under the 'f flap B if it is long enough to require such treatment, and then the cover-flap B is folded down, its edges ressing on the lines of iiimly attachedto the cement F and being fla s on which the cement is applied.

t will be readily seen that my package is of simple construction, which can be both easily made and used, that the scaling is secure both against moisture and with respect ing to the outer casing, and that the completed package has the panels of the outer casing unmarred, so that the labels or decoration appearing thereon-will be in no Wise injured elt er by the manufacture or closing of the box.

Having now described my invention, What I. claim as new, and desireto secure by Letters Patent, is-

' 1. A lined paper box, the lining of which consists of a sheet of paper folded into the form of a rectangular box, and' the outer shell of which consists of a blank folded over the lining and having perforated flaps folded over each other and secured together and to the material extending through the perforated aps to the end Wal inner lining by cementin of the lining.

2. A lined paper box, the lining of which form of a rectangular box, and the outer shell of which consists of a blank folded over the lining and having flaps folded overeachother flap or flaps erforated and said flaps being secured toget er and to the lining by cementmaterial extending from the inner face of the unperforated outer fla through the perforated flaps to the liningox.

3. A lined paperbox, the lining of which consists of a sheet of paper folded into the form of a rectangular box, and the outer shell of Which consists of a blank folded over the consists of a sheet of paper folded into the and over the end Wall of the lining-box, the outer flap'being unperforated'and the inner
